5 wood heater having means to automatically regulate the draft of theheater whereby the desired temperature can at all times be maintained inthe brooder.

Another object of my invention is to provide an attachment of thischaracter which can be readily applied to the ordinary down draft heaterwithout altering the construction of the heater in any way and which hasthe same operation and advantage as a brooder having a speciallyconstructed heater.

A further object of my invention is to provide an attachment of thischaracter in which the automatic control of the damper is so positionedit will not be affected by the direct heat from the heater and in whichthe automatic control can be regulated to the desired temperature.

A still further object of my invention is to provide a simple, cheap andeffective brooder attachment for wood heaters having certain details ofstructure and combination of parts hereinafter more fully described.

In the accompanying drawings:

Figure 1 is a side elevation of an ordinary down draft wood heater withmy attachment applied, forming a complete automatically controlledbrooder.

Figure 2 is a, top plan view of Figure 1.

Figure 3 is a vertical transverse sectional view taken on the line 33 ofFigure 1.

Figure 4 is a vertical sectional view taken on the line 44 of Figure 3at right angles to Figure 3 and looking in the direction of the arrow.

Figure 5 is a vertical sectional viewof a modified form of the downdraft pipe.

Figure 6 is an enlarged perspective view of the base attaching means.

Referring now to the drawings:-

l represents the ordinarydown draft wood heater having the down draftpipe 2 extending upwardly close to the body of the heater to a pointadjacent its upper end. These heaters are mounted on legs and the upperend of the body is provided with a cover 3 by means of which the wood isfed to the stove. The heater is also provided with the usual stove pipe3' extending from the upper end, but this stove pipe could extend fromthe side of the heater. The upper end of the down draft 2 is providedwith the ordinary hand operated shutter damper, as is well understood bythose skilled in the art. My improved brooder attachment comprises acircular band 4 of flexible sheet metal provided with a series ofopenings 5 to allow the air to circulate under the body of the heater.This band is provided on its inner face with inwardly extending 5 lugs 6adapted to be sprung into the socket from which the ordinary legs of theheater have been removed. By this structure it will be seen that thesmall chickens cannot get under the stove or crowd each other due to thefact that the same 10 is of a circular form. The hood 8, forming the topof the brooder, is composed of a conical circular ringhaving the opening9 therein of a size to closely fit the outer wall of the body I of theheater and is supported by means of legs Ill so that its lower edge issupported a distance from the floor so that the chickens can readilypass under the same. In order that this hood may be readily slipped downover the heater, it is provided at one side with a cut away portion llof a size slightly greater than the down draft pipe 2 and thethermostatic control damper carrying housing l2, as clearly shown inFigures 2 and 4. By this structure it will be seen that the hood 8 canbe slipped down around the stove until the legs I0 rest upon the floor.'In order to make a tight fit around the down draft pipe 2 andcompletely close the opening ll, after the hood has passed the automaticdamper control housing I2, I provide two sheet metal plates l4 and I5pivoted at l6 to the hood 8 and having their inner edges I1 and I8arranged in an arc or circle to correspond with the body of the heater 1In beyond these curved edges, the plates are provided with cut away 35portions l9 and 20 adapted to correspond with the curve of the downdraft pipe 2 and whereby the plates l4 and I5 are moved inwardly and atight fit is made with the body of the stove and the down draft pipe toretain the heat under the hood. In order to hold the plates in theoperative position, I provided buttons 2| and 22 which are adapted to beturned over the edges of the plates I4 and I5 to hold them in theiroperative position. 45

The ordinary wood heater of this type, as heretofore stated, is providedwith a hand operated damper at the upper end of the down draft pipe.This damper is in the form of a cap efiect extending around the upperend of the down draft pipe and bolted thereto, which bolt extends overand secures the draft pipe to the body of the stove.

In converting this ordinary wood heater to a brooder. this cap isremoved and a cap 23 is placed
